' This invention'lrelatesto hose and more especially to-hosehaving relatively thin, flexible walls such asfirehose.

The principal object of the. invention is'toprovide increased life of the hose and to I 7 provide graduallyincreasing rigidity to the hose adjacent its couplings. 7

Other objects will appear from ing description and the accompanying drawg 7 v v Referring to H a section of a length of hosehaving a rigid coupling men'iber secured thereto, the device being shown partly in section, parts being broken away, the numeral 10 designates the rubber lining which extends throughout the length of the hose, and the numeral 11 the woven jacket extending thereover. One of the coupling members 121s shown as mounted on one end of the hose, thehose extending partly through the coupling member, and being held in secure engagement therewith by a metal-ring 13 inserted within that part ofthe hose extending within the coupling -member, and expandedin place to clamp the Walls of the hose againstthe serrated wall of the coupling member. A reinforcing layer of fabric 14 is assembled between theplies fl.

of rubber constituting the rubber lining and extends only a short distance from the ,Jcoumade oftire breaker fabrichavingits threads or cords extending at'anacute angle tothe axis of the hose. That end of the reinforcelnent extending away from the coupling is preferably notched deeplyto providea" lish tailedmargin 15 whereby therreinforcin'g In the manufacture of hose ofthis construc-" tion the jacket is first wovenand cut to the desired length. The rubber lining is then prepared by seaming the longitudinal edges of" a sheet of rubber of the same length i as the jacket. The fabric reinforcements 14 are laid between plies of the'rubber sheet at its ends. The rubbertube'reinforced with fabric at'its ends is then; pulled through the jacket and vulcanized in place by internal pressure.

The ends ,of the hose are trimmed,' the c 0u the followan all-rubber liningtherefor', a coupling mem- 1932. S eria1 No. 610,84 6. ,and-the sharp bending of the hose whereit meets the ,coupling. 1 It distributes any longitudinal I strains, such as are caused by pulling the hose,

over an increased area and transmits them v v from the coupling to the jacket at a position the drawinghich illustrates remote from that at which the cords of the.

jacket are subjected to pinching by comsharply defined bending Zone will be present in the hose near the coupling. The extension m of the rubber of the lining between the end reinforcement. and the jacket provides for equalizing. the distribution. of strains to all the horizontal cords of thejacket, and the-extension of the rubber a cket overv the inside of theireinforcement provides for protection of the, reinforcement from moisture.-

tenai'rc'eexpense by reducing the necessity for pling. This reinforcement is? preferably renewing couplings to that due to, actual coupling'we'a'r. The presence ofithereinforceber lining due to age.

Iclaim: v

1." 'A hose comprising textile jacket and biervv engaging an end of the hose, and a reinforcement comprising a bias-laid collar. of

textile material extending from thatportion' I I of thebase engaged by the coup'ling'only to "a zone of the hose adjacentj thereto for dis:

tributing longitudinally applied strains from thecoupling member'to a substantial area ofthe jacket.

2, A hose comprising a woven jacketand 1 an all-rubber lining therefor, a"coupling member .engagingan end of the'hose, and a "160 Alliof these features contribute to the life .of the hose and'to the reduction of mainreinforcing layer of bias-laid breaker fabric extending only through that portion of the wall of the hose engaged by said coupling member and closely adjacent thereto.

3. A hose comprising a jacket and an allrubber lining therefor, a coupling member engaging an end of the hose, and a reinforcing layer of breaker bias laid fabric extending only through that portion of the Wall of the hose engaged by-said coupling member and closely adjacent thereto, the margin of said reinforcement remote from said coupling being inclined to a plane perpendicular to the axis of the hose.

4:. A hose comprising a jacket and an allrubber lining therefor, a couplingmember engaging an end of the hose, and a reinforcing layer of bias-laid breaker fabric extending only through that portion of the Wall of the hose engaged by said coupling member and closely adjacent thereto, the margin of said reinforcement remote from said coupling being notched to provide a fish-tail along that portion of the hose engaged by said coupling and closely adjacent thereto,

said reinforcement being less flexible at the coupling than at its margin remote therefrom.
